Specific mast maintenance
Checking the condition of mast mounting
and its chains
– Thoroughly clean the mast guide rails and
the chains.
– Inspect surfaces for wear and check rota-
tion of rollers.
– Inspect the chains for wear, especially
around the return pulleys.
– Check the chain fixings and anchorings.
– Replace any worn chains, or any chain that
is stretched by 3 %.
– Inspect the fixing elements between the
mast and the chassis.
– Inspect the fixing collars of the mast cylin-
ders.
Adjusting the length of the mast chains
NOTE
Depending on the use of the truck, the chains
are liable to stretch and as a result they have
to be adjusted regularly.
– Lower the mast completely.
– Undo the lock nut (2).
– Place the chains under slight tension by
tightening the nut (1).
– Retighten the lock nut (2).
CAUTION
Deterioration or destruction of the equipment.
After this adjustment, check that the lift carriage
does not reach the mechanical stop at the top of
the mast. If this is the case, slacken or change the
chains. We advise you to entrust this operation to a
specialist within our network.
Cleaning and lubricating the chains
NOTE
If the lifting chain is too dirty, clean it.
– Place a recipient underneath the elevator.
